Best answer here is to use what Apple documents: MacBook Pro: How to remove or install memory. Here's what Apple states:

MacBook Pro (13-inch, mid 2012)

  • Number of memory slots 2
  • Base memory 4 GB
  • Maximum memory 8 GB

Memory card specifications:

  • Double Data Rate Small Outline Dual Inline Memory Module (DDR3) format
    • 67.6mm x 30mm (1.18 inch)
    • 2 GB or 4 GB
    • 204-pin
    • PC3-12800 DDR3 1600 MHz type RAM

Additional notes: For best performance, fill both memory slots, installing an equal memory module in each slot.

I should point out this listing is a bit dated as this series can support 8 GB modules so you can go up to 16 GB of RAM.

Thansk! So just to be clear, this is the 1.5v 'normal' DDR3? :)


DDR3L is a dual voltage capable memory DIMM, which supports operation at both 1.5V and 1.35V. DDR3L is also pin-compatible with DDR3.

DDR3 is a single voltage capable memory DIMM, which supports 1.5V operation only.

Basically you can use either but the older DDR3 is cheaper.


Thanks a lot!
